Abstract
A tire comprising: two beads intended to be in contact with a mounting rim (J), at least one of the said beads having a bead seat inclined towards the outside, this bead comprising an anchoring device formed by at least one circumferential bead reinforcement element and a wedge substantially triangular in shape, a radial carcass reinforcement having an upturn extending over or in the wedge, and axially outside the lateral face of the wedge, a protuberance made from rubber mix provided for axially protecting the rim (J) against abrasion and impacts when the tire is mounted on the latter, each bead comprising, between the axially external protuberance of the said bead and the lateral face of the wedge, a bead protection profile with a thickness of at least 0.3 mm made from rubber mix whose modulus at 10% deformation is greater than the modulus of the material constituting the protuberance.
